- Hi Steve, I'm glad to hear you're back on the road, but since the ammeter should not have been part of the fan circuit to begin with, the fact that bypassing the ammeter cures your symptoms should gi

- Theo: I appreciate your comments, but the ammeter's inability to carry high voltage is verified by the fact that, with it gone, the wire overheating problem is also gone. All of the other wiring on m

- Well, maybe Theo's analogy was a wee bit of a hyperbole Steve, but your explanation doesn't wash either. First off, I also had a problem with my ammeter overheating; it was just the connections on t

- The ammeter will definitely get warmer the more current you push through it, exactly as Bob describes, but not to 190 degrees, unless you're driving it way beyond its rating. What I've been trying t

- An ammeter is SUPPOSED TO BE A SHORT, or at least be as close to zero ohms as possible. You are trying to measure the current in a wire while causing only a minimal voltage drop. If it is working pro

- That's correct, but that is not how an ammeter is supposed to be wired (at least not when it's used in a vehicle application). On the Tiger, you should have a 10 gauge wire running from the battery c

- As Bob alluded to earlier, the amount of heat generated in a resistance is given by the square of the current (in amps), multiplied by the resistance value in Ohms. Components do not "cause" resista
